HEDGE TRIMMER.

Application led October 14, 1924. Serial No. 743,567.

This invention relates to a machine for trimming hedges and aims toprovide a machine which may be operated adjacent to a hedge in a mannerto evenly cut the hedge.

An important object ot the invention is to provide a machine ot thischaracter wherein the cutter bar thereof, may be moved to Operate in ahorizontal plane or a vertical plane so that the machine may beconveniently operated for trimming the sides as well as the top of thehedge.

Another object of the invention is to provide a hedge trimming machinewherein the cutting bar may be adjusted to operate at various heights.

With the foregoing and other objects 1n view which will appear as thedescription proceeds, the invention resides in the combination andarrangement ot parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the .invention herein disclosed, may be made within thescope of what is claimedtwithout departing from the spirit of theinvention.

Referring to the drawings:

Figure 1 is a side elevational view of a hedge cutting machineconstructed in accordance with t-he invention.

Figure 2 is a plan view thereof.

Figure 3 is a rear elevational view of the machine.

Referring to the drawings in detail, the machine includes a body portionindicated generally by the reference character 5, which body portion issupported on the axles 6 and 7 respectively, on which the wheels 8 aremounted.

The wheels on the axle 7 are secured fast to the axle so as to revolvetherewith. Mounted on the axle 7 is a sprocket 9 that transmits throughsprocket chain 16 and sprocket 10 mounted on shaft 10 movement to saidshaft mounted at the forward end of the body portion and operating inbearings 11, and which in turn transmits movement to the power shaft 12through the sprockets 13 and 14 mounted on shafts 10 and 12 respectivelyand the chain. 15 operating thereover.

The shaft 12 is carried by the pivoted frame indicated generally by thereference character 16 which frame includes side bars 17 that have theirrear ends extending beyond the rear of the body of thel machine wherethey are connected by the bar 18 that provides a handle for the machineand atlords means whereby the machine may be manually moved.

Extending to a position adjacent to the handle 18 is a steering rod 19of which the forward portion ends in a bell crank pivotally connected asat 19 to the bar 2O that is supported under the frame, one portion otsaid bell crank extending at right angles to the other as at 21 where ithas pivotal connection as at 20 with the guiding link 22 which ispivotally connected as at 21 with the support 23 that carries the frontaxle 6. Thus it will be seen that the operator may, by moving the rod19, readily and easily control the movements of the machine to properlyguide it in its work.

Bearing members 23 are carried by the pivoted :traine 16 and support theshaft that is supplied'with a beveled pinion 25 meshing with beveledpinion 26 so that rotary movement of the shaft 12 is imparted to theshaft 24.

At the end of .the shaft 24 is a balance wheel 27, while at the oppositeend ot the shaft 24 is an eccentric 28 to which the connecting rod 29 isconnected. The connecting rod 29 is also pivotally connected to themovable cutter bar'SO through the medium ot' the arm 31 so that rotarymovement oi the shaft 24 is converted into a reciprocatory movement foroperating the cutter bar.

The reference character 32 indicates the lower section of the cutter barand, as shown, is pivotally connected to the traine 1G at whereby thecutter bar may be swung in a vertical plane to various positions withrespect to the machine. This cutter bar includes an arm 34 which isrelatively long and extends to a point adjacent to the opposite side otthe body of the machine when the cutter bar is operating in a horizontalplane.

Associated with the arm 84 is an upwardly curved bracing member 35 whichhas one end thereof formed into a. support 36 so that when the cutterbar is moved to a position to operate in a vertical plane, the cutterbar will be supported and held rigidly with respect to the body ot'V themachine. In order that the cutter bar will be held in its verticalposition, openings 37 are provided in the member 35 for the receptionot' the pin 38.

From. the oreging itwill be obvious that due to this construction, thecutter bar will be moved to a position to operate either in nl ...t

a horizontal plane or a vertical plane, to the end that the top as vvellas the sides of the hedge may be readily eut with the machine.

At the rear end ot the inachine are upwardly extended arms 39 which arepro vided with notches Ll() for the reception ot the bar 4l that iscarried by the pivoted frame 1G, the bar acting as a. mea-ns to supportthe frame 16 in various positions ot vertical adjustment to gauge thecutting depth of the cutter bar.

l. A hedge trinnning machine embodying a wheel-supported trame havingupwardly extended arms at the rear thereof, said arms heilig providedwith notches, a trame mounted on the wheel-supported irame and havingits 'forward end pivotally connected to the first mentioned trameadjacent to the forward end ot the wheel-supported trame, actuatingmechanism mounted on the second mentioned i'rame7 a cutter har operatedby the cutter har actuating mechanism, and a movable bar carried hy thesecond mentioned i'rame and adapted to he moved into the notches ot theupstanding arm to adjust the second mentioned frame vert-i "ally,

2. A hedge trin'iming machine emhod ying a wheel-supported frame havingupwardly extended arms at the rear thereof, an auxiliary pivoted tramemounted ahove the Wheel-supported 'trame and connected thereto, a cutterhar actuating mechanism carried by the auxiliary frame, a cutter haroperated by the cutter bar actuating mechanism and extending laterallytherefrom in a. horizontal plane, and means for adjusting the auxiliaryframe vertically to adjust the cutter bar.

3. A hedge trimming machine comprising a wheel-supported trame, an.auxiliary trame supported by the l'irst mentioned trame, a cutter haractuating mechanism carried hy the second mentioned trame, a cutter haroperated hy the actuating mechanism and extending laterally from themachine, means for adju ting the auxiliary 'trame vertically to raise orlower the in a harizoutal plane7 and adjustable means' on theauxiliaif,v trame for holdingl the cutter in a vertical position.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature.
